Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628264, here are decompositions:

31 + 8628233 = 8628264
61 + 8628203 = 8628264
83 + 8628181 = 8628264
103 + 8628161 = 8628264
107 + 8628157 = 8628264
157 + 8628107 = 8628264
167 + 8628097 = 8628264
233 + 8628031 = 8628264

Showing the first eight; more decompositions exist.
